Title: A carrier supply circuit for carrier telephone systems
IPC: H04J1/06
Filed: 1955-08-18
Abstract: 812,959. Valve generating circuits. SKILLMAN & CO. PTY. Ltd., T. S. Aug. 18, 1955 [Aug. 23, 1954], No. 23847/55. Class 40 (6). [Also in Group XXXIX] A valve oscillator is arranged to supply a plurality of loads L1, L2 which may be modulators in a multi-channel carrier telephone system, through the transformers T1, T2 having their primaries connected in series in the anode circuit of the valve. The impedance presented by the valve to the circuit is arranged to be high compared with that presented by each transformer primary whereby the coupling between the loads is kept at a low value; thus in a multi-channel carrier telephony system the cross-talk between channels is kept at a low level. The oscillator comprises a four-electrode crystal P interconnecting the screen and control grids of the valve V provided with an unby-passed cathode resistor R6 to increase its output impedance. Amplitude control of the oscillator output is provided by rectifier RF whereby a negative control voltage which is applied to the control grid of the valve V is derived from the oscillatory voltage developed across the primary of transformer T1. A potentiometer network PR provides a delay whereby in the absence of fed-back signal, grid current flows and the impedance in series with the crystal in the grid circuit is kept at a low value; it is stated that this ensures that the circuit commences oscillating at the fundamental frequency of the crystal. In addition, owing to the delay the build-up of oscillations after any interruption takes place more rapidly than would otherwise be the case.

Abstract: 1,219,463. Collagen film. JOHNSON & JOHNSON. 20 May, 1968, No. 23914/68. Heading B5B. An edible, heat sealable film at least 90% soluble in water at 70‹ C. and has a tensile strength of at least 10,000 pounds per square inch comprises collagen; the molecular weight of which has been altered by contact with a dilute acid solution of a proteolytic enzyme, and it has a free tyrosine to hydroxy-proline ratio of at least 0À062. The collagen may be obtained from the corium layer of hides. Proteolytic enzymes which may be used are bromelain, ficin, papain and proteolytic enzymes produced from genus aspergillus. Plasticers such as glycerine, sorbitol, propyleneglycol or corn syrup may be added to the modified collagen in amounts up to 50% by weight of the dry collagen solids. In addition, other film ingredients, such as, starch, vegetable gum, vegetable cooking oil, edible cellulose derivatives, gelatin, flavouring agents, colouring agents, anti-oxidants and emulsifiers may be added to the enzyme-modified collagen. Films of the enzyme-modified collagen may be prepared by grinding an aqueous slurry of collagen together with an enzyme and acidifying the mixture with an edible, non-toxic acid, such as citric acid. The acid-swollen collagen is stored for several hours at room temperature, then homogenized and de-aerated before it is extruded to form a film.

The coned outer end 1b of the sleeve 1, 1a engages a fixed cone 7 secured to an anchoring arm 8, and the sleeve is keyed to the cone 7 by a key 9 on the latter. The coned outer end of the brake sleeve 2, 2a is engaged by a main actuating cone 12, which during back-pedalling is moved axially by the roller-carrying part 13 of a free-wheel clutch, e.g. through the action of inter-engaging ratchetshaped parts 14, 15, whereby the sleeves 1, 2 and the ring 5 are forced towards the fixed cone 7, the conical surfaces causing the sleeves to expand into braking engagement with the hub shell 3. The actuating cone 12 is held against rotation during back-pedalling by a roller clutch 17 engaging the inner surface of the brake sleeve lining 2a, the roller cage being provided with drag springs 18 of blade form.

Abstract: 1,272,629. Phosphoric acid from phosphate rock. DORR-OLIVER Inc. 13 May, 1969 [13 May, 1968], No. 24402/69. Heading C1A. A process for making phosphoric acid comprises the acidulation of phosphate rock with sulphuric acid to produce phosphoric acid and gypsum, wherein the sulphuric acid for the acidulation is prepared by (1) reacting ammonium fluosilicate with molten ammonium bisulphate to produce an ammonium sulphate melt and fluosilicic acid and (2) reacting the fluosilicic acid with an ammonium sulphate solution to produce the sulphuric acid and ammonium fluosilicate, which may be recycled to be reacted with ammonium bisulphate. The gypsum produced in the digestion step may be reacted with ammonium carbonate to produce an ammonium sulphate solution and calcium carbonate, and the resulting ammonium sulphate may be recycled for reaction with the fluosilicic acid. The phosphoric acid produced from the digestion may be concentrated preferably at about 80C. to precipitate ammonium fluosilicate crystals, which can be recycled for reaction with the ammonium bisulphate. The ammonium sulphate melt produced in the process may be decomposed in the presence of, for example hot CO 2 , to produce ammonia and ammonium bisulphite, the latter being recycled to react with the ammonium fluosilicate, and the former being reacted with CO 2  and H 2 O to produce ammonium carbonate which is recycled for reaction with the gypsum.
